a Claims. (01. 98--106) This invention relates to air register grilles of the character usually employed domestically at the outlet of hot air ducts, and the primary object of the invention is to provide a more eiilcient. effective, and yet less expensive assembly that will have a neat'appearance and have a high percentage of opening relative to the-size of the duct which it covers. n One of the important features of the present invention is the provision 'of a unitary face plate. for air registers of the aforementioned character that is formed of a single piece of sheet metal so as to present a plurality of angled bailles. between which the air currents may pass and because of the angularity of said bailles, said air currents may 'be deflected so as to direct the same to the largest possible portion of the room that the air register is serving.

Still further objects of this invention are to arrange the aforesaid bailles at angles to the perpendicular to the ordinary, normal plane of the plate which increase as the ends oi the plate are approached from the vertical center; to provide a specially formed frame or marginal portion at the edges of the plate so that the register may be sealed in position; and to provide a damper for effectively closing the openings of the register, said damper having novel mounting and actuating means of the nature hereinafter fully set down,

Structural features of the air register grille form other objects of this invention and the same will be made clear during the course of the following specification, referring to the accompanying drawing, wherein:

embodying this invention.

Fig. 2 is a horizontal cross section through the same, taken on line IIII of Fig. 1.

Fig. 3 is a vertical cross section taken along line UL-III of Fig. 1.

Fig. 4 is an enlarged, fragmentary, rear elevational view illustrating the spring hinge which mounts the damper, and,

5 Fig. 5 is a detailed view showing the-slot for receiving the operating chain for the damper.

As is well known in this art, such register assemblies as shown in the accompanying drawing are usually placed on the wall 8 of a building wherein D is built an air duct or similar passage l0, through which is introduced hot or cold air from heating or conditioning plants remotely. located. The air register grille embodying the preferred form of this invention has a unitary face plate l2, through 5 which is cut aseries of elongated, parallel slits ll- Figure 1 is a face view of an air register grille for the passage of currents. After these slits are cut, the material of the plate is bent to form a number of loailles it, all of which are disposed at angles with respect to the normal plane of plate i2 and with respect to a line extending perpen- 5 dicularly therethrough. A central, vertical panel l8 remains in the plate and baflles it on each side respectively of this panel are angled so that the degree of angularity is increased from the aforesaid perpendicular line toward the ordinary, norl0 mal plane' of plate iii as the outer ends of plate l2 are approached.

In so forming bailles It, the air currents are introduced into the room enclosed by walls 8 in an even and properly diffused manner. Said baflies prevent blasting and the evenness of introduction is further accentuated by the structure in that the space H between proximal ends of baflies It allows a certain amount of the air to pass directly from the register grillein lines perpendicular to the plane thereof..

Plate I2 has a continuous, laterally extending flange 20 formed therearound to co-operate with a laterally pressed head 22 informing a channel for the receptionrof calking or sealing compound 25 24 thatprevnts leakage from duct I8 between wall 8 and the side of plate l2. Plate I2 is also pressed inwardly as at 26 to present a coasting angled wall for damper 28.

Damper 28 is hingedly mounted as will be pres- 30 ently described and has a laterally extending marginal wall around the edge thereof to lie snugly against wall 26, whereby to efiectively seal together plate i2 and damper 28. Hinge 32 which mounts damper 28 and secures the same to plate 35 i2, is provided with a spring 84 that urges damper 28 toward the open position. Hinges of this nature are well known and the use of such a hinge in a register grille has been found to be exceptionally effective. 40

Means for operating damper 28 is provided in the form of a chain 36. This chain is anchored at its one end to damper 28 through the medium of a resilient yoke 38 that may give or spring as damper 28 moves to an angle with respect to plate I2. This resiliency of yoke 38 also permits positioning of chain 38 so that the links thereof may -be moved to a locking condition with a link on each side of plate l8. Chain 86 passes through a specially formed hole 40 provided through panel I8, as illustrated in Fig. 5, and when chain 36 is pulled through the large upper portion of hole 40, it is free to move but will be locked against move-. ment when the links of chain 35 are moved downwardly into the narrower portion of hole 40,

Means for holding the entire air register assembly in operative position is here shown to be the inwardly extending fixtures 42 that may be fastened to wall 8 by screws or analogous units 44. These fixtures are L-shaped and one leg is fastened to plate l2 as at 46.

The operation, advantages and desirable features of this register grille have become, apparent during the foregoing description, and attention y of wall 8.

Having thus described the invehtion, what is claimed as new and desired to be secured by Letters Patent is:

1. An air register grille comprising a polygonal unitary face plate provided with a series of openings therethrough; a continuous, laterally extending flange at the edges of said plate; a laterally projecting bead formed in the plate, and extending outwardly therefrom on the same side thereof asthe flange coextensive with the flange and in spaced, parallel relation thereto whereby to form a channel for the reception of calking compound when the grille is set in place; and a hingedly mounted damper movable to and from a position closing said series of openings.

2. An air register grille comprising a polygonal unitary face plate provided with a seriesof parallel slits therein; a damper movable to and from a position closing said slits, and a spring hinge supporting the damper, the material of said plate between said slits being disposed at an angle to the normal plane of the face plate to provide bailles to deflect the air currents passing through said slits in directions other than perpendicularly tothe normal plane of said face plate, said plate having a panel intermediate the ends thereof, the bailles between said panel and the respective ends being disposed at progressively greater angles to the perpendicular to said face plate as the ends 'are approached, the bailles all being arranged to direct currents of air outwardly from the said panel toward the ends of said plate, the said baf-' fies being disposed in spaced relation to afford an unrestricted slit between proximal side edges thereof to permit a certain amount of air currents to pass through said plate along paths perpendicular tothe plane thereof, said damper being swingable to and from a position against the inner edges of said baffles, the damper having op erating means in connection therewith and extending through the said panel, said spring hinge being arranged to constantly urge the damper to the open position against the anchoring force of said operating'means.
